CAR ROOF.

Application filed September 15, 1921. Serial No. 500,768.

To @ZZ ily/i077?, t 'may concern.

Be it known that l, JOHN Pnnnson, a citizen of the UnitedC States,residing at Chicago, in the county oi" Cook, State of lllinois UnitedStates of America, having invented certain new and useful improvementsin Car Roofs, do hereby declare that the following is a full7 clear, andexact de scription of the saine.

lily invention relates to car-roots, and consists in the novel anduseful constructions herein described and then pointed out in theappended claims.

ln the accompanying drawings7 which illustrate practical embodiments ofthe vari ous features of my invention and in which the same referencenumerals indicate siniilar parts in the different figures, F l is a t fpplan view of part of a car-root embodying the features ot my inventionwith various parts cut-away to atlord better illustration; Fig. 2 is across-sectional view along the line of one oi the carlines with itstopcap and end-cap omitted; Fig. 3 is a. detail sectional view oit oneor the carlines and associated parts; Fig. l is a detail view partly insection and partly in perspective showing one of the end-caps in place5and Fig. 5 is a detail sectional view on the line 5--5 in Fig. l.

ln the drawings the reference numeral l indicates the ridge-pole, 2 theside-plates. 3 the side-sheathing, 4 the end or body carlines, 5 thelongitudinal wooden purlines, and 6 the roof-boards extending from theridge-pole to the side-plates; the ridge-pole and body ca-rlines areoppositely inclined from their centers to contorni to the pitch of theroof. Extending transversely or' the roof at suitable intervals are thecarlines which in the present invention are composed of woodensub-carlines 7 and metal topplates 8 extending from the ridge-pole tothe side-plates. The bodies of the sub-car`- lines 7 are rabbeted ateach side to form seats for the sides of the metallic roof-panels 9, andthey are bolted to the ridge-pole and purlines by bolts l() having theirheads countersunk into their ridges or raised cen trai portions ll. Thetop-plates 8 are of less width than the lower portions of thesub-carlines, but are wider than their ridges to which they are securedby wood-screws 12 having their heads countersunk therein. The inner endsof the opposite sections of each cai-line are straddled by a suitablemetallic ridge-cap 13 which is bolted as at le to the ridge-pole. Theouter end of the body of each subcarline is shouldered or cutaway on itslower side at l5 to allow its ridge ll to overlie a wooden strip i6arranged upon the side-plate 2 aga-inst which the outer ends of the1.'ooi-l: oards 6 abut, and the outer end oit each 'top-plate S isreduced in width to form a depending wing il" constructed to be bentdown over the t'aeia i8. ifi iflrashing 19 is arranged upon the stri )s16 and acias 1.8 to underlie the outer ends of the ridges ll androot-panels 9, and a carline end-cap 2O fits over the outer end ot eachcarline, being secured to the wing 17 by a. bolt 2l and having alag-screw Q2 passing through its skirt into Ythe sideplate. Thetop-plate thus forms a` fastening or anchor for the end-cap.

The roeic sheets or panels 9 extend from the ringe-pole outward to theeaves resting upon the flanges ot the carlines and the flashings; eachsheet or panel is substantially rectangular in shape and is providedwith the usual upturned side-iianges 23 that lie under the plates 8 ofthe carlines, with sullicient clearance between the parts to allow playto the plates along their length. The seats for the roof-panels formedby the side flanges et the carlines are straight from end to end and thewebs or ridges ll are of uniform height so that the roof-panels arecarried on the carlines with their flanges under thev top plates uponwhich the carlinecaps are in turn supported so that all these parts areinterlocked.

The carline-caps are formed oit sheet metal of inverted trough-shape incross-seo tion. each consisting of an upper horizontal top 24 ofsuilicient width to overlap the car line-plate 8, sides 25 of suilicientdepth to iorin a skirt reaching to the panels, and inwardly directedflanges 26 bearing on adjacent panels; they extend from the ridge-'poleto the eaves, and each is provided with opposite inwardly projectingribs 27 in its sides 25 which engage the under faces of the top plate Sof the carline. These ribs are formed by inwardly bending or swaging thematerial of the sides at a. suicient dista-nce below the top to providean intervening passage or channel to snugly receive the edges of theplate1 and preferably are at the center of the sides, leaving the endsthereof plain extending along the center ot the sides a sutlicientdistance to firmly lock the caps on the cai-lines. After the roof-panelsare assembled upon their supporting bases between the carlines, thecarline-caps are -slipped into place on the carlines with their ribs 27under the carline plates 8, each being slid along the length of theassociated carline beginning at its outer end from the eaves to theridge-poles and its sides 25 enclose the flanges 23 of the adjacentpanels; When the cap is in position it is held against verticaldisplacement by its ribs, and its lateral flanges 26 hold the associatedpanels down on their bases, those parts thus being interlocled togetherto hold the panels and caps in place and provide a -weather-prool joint,but leaving sullicient clearance between the flanges and the earlinesand caps to provide a flexible joint to permit the panels to move un derstrains or twisting actions t' the car and so prevent the buckling oftheir bodies or the fracture of their joints. The end-caps are thenpositioned overthe outer ends or the earline-ca )s and the Wings of theplates 8 to which they are bolted as at 2l, and are fastened to thecar-body by the rlag-screws 22, and the ridge-caps 13 are positionedover the inner ends of the. carline-caps; the caps also carry thesaddles2S for the running-boards 29.

The oai-line composed of the Wooden body and metal top-plate is ofadvantage in making repairs and replacements oit car-roots, as the partsare easily and quickly 'assembled Without disturbingsurrounding-elements, and the cost of an all-metal carline isappreoiably reduced Without sacrilicing any util-ity as a base for theadjacent sheets or panels and to which kthey can be interlocked by thecaps.

I claim:

l. ln a car-roof, a carline composed of a Wooden body having a centralridge and a metal top-plate secured to the ridge and eX- tending beyondits sides from the ridge to the eaves, roof-panels adjacentthe carlinesand having upturned lateral flanges adjacent the ridges thereof andunder the topplate, and a cap on the plate covering the flanges ofadjacent panels.

2. ln a car-roo', carline composed of a Wooden body having a centralridge and a metal top-plate secured to the ridge and eX- tending beyondits sides from the ridge to the eaves, rooitpanels adjacent the carlinesand having uptnrned lateral flanges adjacent the ridges thereof andunder the topplate, a cap on the pla-te embracing the flanges of thepanels, the outer end of the plate providinga Wing constructed tooverlie the end otl the ridge, and an end-cap bolted to the wing.

3. ln a car roof, a carline composed oi' a Wooden body having a centralridge and a metal top-plate secured to the ridge and eX- tending beyondits sides, root-panels adjacent the carlines and having upturned lateral langes adjacent the ridges thereof, a

Arap on the carline having sides extending down upon the panels outsidetheir flanges and provided with inwardly directed ribs to enga-gethesides of the plate, the outer end olE the plate forming a Wing tooverlie the outer end of the ridge, and an end-cap bolted tothe Wing.

et. ln a oaraooi, a carline composed of a Wooden body having a centralridge and a metal top-plate secured to the ridge and extending beyondits sides and outer end, the body being cut-away atits outer end, aflashing-strip under the carline-ridge, the outer end oi' the top platesforming a Wing to overlie the end of the ridge, roof-panels adjacent thecarline having flangesa carlinecap embracing the plateV and coverine thehanges, and an end-cap on the end or the farline-cap and bolted to theWing.

In testimony whereof l ailix mylsignature.
